A zoo keeps endangered animals in enclosures a tiny fraction of their natural range. It also funds breeding programs that have pulled real species back from extinction and teaches millions of children to care about wildlife. Is keeping the animals there justified?

Why this dilemma matters

Public-good questions surface the trade-offs that aggregate numbers usually hide. Choosing “Justified. Conservation and education save whole species — that outweighs the cost to the individual animals” prioritises broader fairness; choosing “Not justified. No mission makes a lifetime in an enclosure acceptable for a wild animal” gives more weight to concrete impact on individuals.

Worth asking yourself

• Would you accept the outcome from the losing side?
• Are we solving the problem or moving it?
